“…The production of O 2 •– in chloroform deserves attention. In some studies, − chloroform has been used as a quencher of O 2 •– , which may lead to a contradiction in the contribution of reactive species . Since no inhibition was observed, O 2 •– is often regarded as ineffective; although the conclusion may be a fact due to the low reactivity of O 2 •– , using chloroform as an O 2 •– quencher is unreasonable and may potentially spread misleading information.…”
